Hallucinogens are grouped into classes—psychedelics, entactogens, dissociatives, and others—based on how they work in the brain and their chemical structure. While these classes have different primary mechanisms, they all can temporarily and profoundly change consciousness, affecting body sensations, perception, thinking, and emotions. These effects likely explain their recreational use, but a growing body of evidence suggests therapeutic applications beyond abuse potential. This review covers data on several hallucinogen classes, focusing on psychedelics, entactogens, and dissociatives, where clinical utility is best documented. It traces historical insights, compares classes from molecular to behavioral levels, and presents up-to-date clinical research with implications for therapeutic value.
